Transcript Plant classification

Plant classification
All plants can be classified into:

Non-flowering

Flowering
Non- flowering plants

They don’t produce flowers, seeds or fruits.

They reproduce by spores.
Mosses and Ferns grow in dark and humid places (moist conditions)
Mosses

Ferns
They are two main groups of
non-flowering plants
Mosses

They are very small plants with:
◦ Leaf,
◦ Tiny stem
◦ Rhizoids (roof structures)
 They support the plant to the soil.
 They don’t take the water from soil.
(stem and leaves absorb the water)
 Their spores are produced in a capsula (at the end of the
filament)
Ferns

They are larger than mosses.

They have:
◦ Stem which grows underground- (Rhizome)
(Roof and leaves grow from rhizome)
◦ Large leaves – (Fronds)
◦ Their spores are formed on the underside of the
leaves – Sori
Flowering plants

They produce flowers and seeds in order
to reproduce, (in only one season of the year)
Gymnosperms
Angiosperms
They are two main groups of
flowering plants
Gymnosperms

They have small, simple flowers.

They don’t produce fruit.

Their seeds are grouped together in cones.

They are perennials /evergreen
(they have leaves all year round)
Angiosperms

They have large, beautiful flowers.

They produce fruit with seeds inside.

They could be deciduous or perennial.
(they lose their leaves in autumn)

Most plants we eat are angiosperm.

Parts of plants

Leaf / leaves: of a plant play an important role in the plant. The leaves capture
sunlight and use it along with carbon dioxide to produce food for the plant. TO
gives off oxygen

Stem: or the trunk are in charge to take water and nutrients to the leaves or
flower

Spores: a primitive usually unicellular often environmentally resistant dormant
or reproductive body produced by plants, fungi, and some microorganisms

Roof: function is absorve water from the soil and take it to other parts of the
plant
Branch: The function of a branch on a tree is to grow leaves to produce
photosyntisis

Flower: contains the reproductive organs of a plant. The main parts of a flower
are the calyx, corolla, staments and pistil.
